%X Detecting dominant points is an important subject in pattern recognition and computer vision. Corner detection and polygonal approximation are two major approaches for dominant point detection. Based on the two approaches, combined methods have been proposed.In this paper, a new combined method is presented to detect the dominant points.The new method first applies a simple corner detection procedure, then adds some points between detected corner points with the value of curvature computation. Experimental results show that the new combined method is more efficient than the conventional methods. And it overcomes some defects in the conventional methods.
